Studies on direct reduced iron melting in induction furnace
Attempts were made to study melting of DRI in a laboratory size induction furnace using molten steel bath as hot heel The induction stirring accelerates the transfer of heat and promotes theIn the first step, iron ore is reduced to sponge iron in a shaft furnace by means of reducing gas In the second step, the reduced iron is melted in the melter–gasifier vessel Reducing gas (CO and H 2 ) used in the reduction shaft is supplied by gasification of coal by means of oxygen, forming a fixed or fluidized bed in the melter–gasifierDirectReduced Iron an overview | ScienceDirect Topics
